我有 Debian 10 系统和 HP OfficeJet Pro 8020 打印机。 Debian 10 不包含该型号的驱动程序。惠普提供手动升级说明对于 64 位 Debian...Debian 版本 6。
您需要首先安装的某些软件包可能已更改名称。我主要是作弊 - 我使用apt build-dep hplip, 从旧的 Debian 版本中获取所有构建依赖项。
构建成功。我现在可以看到我的特定打印机的驱动程序，并且可以在 CUPS 中对其进行设置。我的问题是它无法打印任何内容。
/var/log/cups/error_log包含这一行：

令人困惑的是，有时顺序会改变，因此首先打印“stopped with status 127”。更令人困惑的是，此错误之后还有更多日志消息。其中之一是“断管”，就好像 CUPS 建立了一个进程管道，当 hpcups 死亡时，该管道全部崩溃。

答案1
我确认是库路径的问题：
$ ldd /usr/lib/cups/filter/hpcups | grep libImageProcessor
libImageProcessor.so => not found
请注意手册说明中的此步骤：
./configure --with-hpppddir=/usr/share/ppd/HP --libdir=/usr/lib64 --prefix=/usr --enable-qt4 --disable-libusb01_build --enable-doc-build --disable-cups-ppd-install --disable-foomatic-drv-install --disable-foomatic-ppd-install --disable-hpijs-install --disable-udev_sysfs_rules --disable-policykit --enable-cups-drv-install --enable-hpcups-install --enable-network-build --enable-dbus-build --enable-scan-build --enable-fax-build
中只有几个文件/usr/lib64/，除了其中一个之外，所有文件都是由 hplip 安装的。 Debian 10 上正确的库路径是/usr/lib/x86_64-linux-gnu/.如果您已经使用错误的路径进行构建，请运行make clean.然后，改变说明以使用此配置命令：
./configure --with-hpppddir=/usr/share/ppd/HP --libdir=/usr/lib/x86_64-linux-gnu --prefix=/usr --enable-qt4 --disable-libusb01_build --enable-doc-build --disable-cups-ppd-install --disable-foomatic-drv-install --disable-foomatic-ppd-install --disable-hpijs-install --disable-udev_sysfs_rules --disable-policykit --enable-cups-drv-install --enable-hpcups-install --enable-network-build --enable-dbus-build --enable-scan-build --enable-fax-build
